Area of Orifice given Area at Section 2 or at Vena Contracta Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area of Orifice = Cross Section Area 2/Coefficient of Contraction
a_o = A_f/C_c
This formula uses 3 Variables

Variables Used

Area of Orifice - (Measured in Square Meter) - The Area of Orifice refers to the any opening, mouth, hole or vent, as in a pipe, a plate, or a body.
Cross Section Area 2 - (Measured in Square Meter) - The Cross Section Area 2 refers to the area of cross-section at the throat (venturi meter) of the structure.
Coefficient of Contraction - The Coefficient of Contraction refers to the ratio between the area of the jet at the vena contract and the area of the orifice.

STEP 1: Convert Input(s) to Base Unit

Cross Section Area 2: 1.8 Square Meter --> 1.8 Square Meter No Conversion Required
Coefficient of Contraction: 0.611 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

a_o = A_f/C_c --> 1.8/0.611

Evaluating ... ...

a_o = 2.94599018003273

STEP 3: Convert Result to Output's Unit

2.94599018003273 Square Meter --> No Conversion Required

FINAL ANSWER

2.94599018003273 ≈ 2.94599 Square Meter <-- Area of Orifice
